Ngani ama-PVC ceiling panels akhona kahle kakhulu kuma-ceiling ase-bathroom ne-se-kitchen?

Ukuhlanzwa Kwezinye Iziphumo Zokuhlanza Nokukhathazeka Kwemithwalo Yokuqhubeka Ngokupheleleyo Kwezindawo Eziqhubekayo Ngokupheleleyo Ngokuphakeme

Amaphoyisa nezindawo zokudla ziyabhekana ngokupheleleyo nezindawo zokuhlaza ngokupheleleyo, ukubhekana okugcwele nesilahlazo, nokubhekana nesilahlazo sesithembiso. Lezi zindawo ziyabhekana ngokupheleleyo nezinto ezingavamile—kepha izipaneli zokuhlaza ze-PVC zizakhiwe ukuze zisebenze ngokupheleleyo kulezi zindawo. Izinsiza ezimbili—isibonelo esingasenzi isilahlazo nesibonelo sokukhathazeka kwemithwalo yokuqhubeka—sizakhiwa ngokupheleleyo.

Ukuthi isibonelo sesilahlazo se-PVC sikhathazeka njani ukufihla kwamanzi nokukhathazeka kwemithwalo yokuqhubeka

Ukuthintana okwesibonelo kwe-PVC ceiling panels kukuthi kubhekisele kumfanekiso wokuphambuka kwemithombo yabo. Ngaphandle kwe-mineral fiber noma we-gypsum, okuzokhula umoya ngokuphambuka kwezinye izinto, isibonelo se-PVC sikhulisa umoya noma umoya wokukhula ngaphandle kokufika emthambama. Lokhu kususa indlela yokuthintana yokuphambuka kwezinye izinto: uma umoya ufika emthambama wokugcina, kwenza ukuthi kubhekele kakhulu umoya emthambama ngaphezulu kwe-panel kusukela ekusha kwezinye izinto (ASHRAE, 2023). Izinkumbu zomusha—ezifanayo nezinye izinto ezikhiywa emthonjeni—zidinga kuphela umoya ophakeme kanye nomthombo wokudla wokuzalwa nokuhlanganisa. Ngoba i-PVC ayisiphothi noma iyasihlukanisa umoya, ayinakho umthombo wokudla noma umoya. Ukuthintana kwezinye izinto kuyasebenza futhi ukuthi umoya wokukhula kubeka amaqhina kanye nokuphuma ngaphandle kungakhulisi. Ngakho-ke, i-PVC panels ibe yisibonelo sokuphambuka kanye akakwazi ukuba yisibonelo sokuphambuka kwezinkumbu—kodwa noma kuzo zizindawo zokukhula kwezinye izinto noma ngaphezulu kwezinye izinto zokuphambuka.

Ukuhlanzwa kwe-ASTM E2652-21: Ukwakhiwa kwempilo yokuthi amaphetha ayisisekelo emithombo yezindawo zokusebenza nezindawo zokuphatha izinkomo

Amaphetha okuthi amaphetha akhanyayo asebenzisa izindawo ezinamandla kakhulu kufanele ahlaziywe ngokuphelele, ngokwesibonelo esingapheli. Umthwalo wokuhlanzwa we-ASTM E2652-21 uhlaziywa ukuthi kuyisisekelo sokuthi amaphetha ayisisekelo emithombo yezindawo zokusebenza nezindawo zokuphatha izinkomo ngokwesibonelo esingapheli: amaphetha aphathelwe ngokwesibonelo esingapheli. Aspergillus niger ,Penicillium funiculosum , futhi izimothi zokugcina ezinkulu zemini, emva koko zihlale kumkhathi wokuhlala kwesikhathi sekhanda 95% sokugcina umkhathi wokuhlala kwesikhathi sekhanda ngeminyaka emibili nezintathu. Ngokwesibonelo sesithombe sesifundo sezinto eziyisisekelo esingaphansi kwe-2023, izipaneli zokugcina ze-PVC ziyasebenza ngokuphelele ukuthi zinombolo 0 noma 1 kusikala se-ASTM—okusho ukuthi akukho ukuthi izimothi zihlale kahle noma kufuphi kakhulu—ngakolunye uhlangothi izipaneli zokugcina zezindawo zokuhlala ezingavamile ziyasebenza ngokuphelele ukuthi zinombolo 3 noma 4, okusho ukuthi zinombolo enkulu yokugcina umkhathi wokuhlala kwesikhathi sekhanda. Yenzwe ukuthi ibonise ukuthi umkhathi wokuhlala kwesikhathi sekhanda ophambili nokuhlala kahle kwezindawo zokuhlala zezindlu nezindawo zokusebenza zokudla, lokhu kubonisa ukuthi i-PVC ayikwazi ukuthi izimothi zihlale kahle ngemikhathi eyisisekelo yezindawo zokuhlala zezindlu nezindawo zokusebenza zokudla. Abafundi bokusebenza kwezindawo futhi abantu abasebenza emzini bafumana isibonelo esisodwa, esibonakalayo sokuthi i-PVC isebenza ngokuphelele lapha ukuthi ukuphatha kanye nokuhlela kungabikho kuzo zonke izindawo.

Ukusebenza Kwempilo Yezipaneli Zokugcina Ze-PVC Emizini

Amakithini ayathumela izinkampani zokupheka ngokuthi zibhekise amaswidi ayo kwezinto ezihlukahlukene: umsindo wokupheka, umsindo wokupheka ophakeme ukuthi wobuhlungu, nokuthi kubekhona isitha esikhulu. Izipaneli zokupheka ze-PVC zazisibonisa ukuthi ziyasebenza kahle kulezi zinhlobo zezindawo ezingavumelekile—kuzokwenzeka ukuthi zibe nesiqiniseko sezinsimbi nezinhlobo zokubona ngaphandle kokuthi izinto zokupheka zingavumelekile.

Ukuqinisa Umshindo, Umshindo Wokupheka, Nokuthi Kube Nisitha Ngaphakade

Isilwane se-PVC esisodwa ngokupheleleyo, esingasenzi ukuthi kubhukwe amafutha okupheka nokuthi kubhukwe amafutha okuhambana ngokushesha—izinkinga eziphakanyiswa kakhulu zokubhukwa nokugula kwezincwadi ezinamaphuzu. Ngokuphulaphula kwezincwadi zeminyawo noma kwezincwadi zegipsi, ozokwenzela ukuthi zihlabe uma zibhukwa ngomoya wokuvula, i-PVC iphila ngokupheleleyo ngoba ayikubhukwi umsindo. Umoya wokuvula uyabeka amadropi futhi uyahamba ngaphandle kwezincwadi ngaphandle kokufika embonweni, okususa izinkinga zokuhlaba kwezincwadi noma ukuthi zihlabe. Emazwini okuzojiza okuphakathi kweminyaka eyishumi yokusebenza kwezincwadi zeminyawo zokupheka, okuphakathi kwezincwadi zokuvula nokufutha (ASTM G154, 2022), izincwadi zase-PVC zazikhubaza izinkundla zabo zezimitheli zezimitheli zokupheka ngaphezu kwe-95% futhi azazibonisi ukuguqula kwezinkundla. Ukuthi kuyatholakala ngokupheleleyo kwezincwadi zokupheka kuyakunceda ukuthi akwazi ukuthi kubhukwe ngokupheleleyo ngokuphakama kwezimitheli—lokhu kuyisimo esipheleleyo sokugula kwezincwadi ezikhulu. Ukuchitha ngokupheleleyo ngamadepa amancane awavula amafutha ayakunceda ukuthi akwazi ukuthi kubhukwe noma kubhukwe ngokupheleleyo, okunika ukuthi kuyatholakala ngokupheleleyo kwezincwadi zokupheka ngaphezu kwezincwadi zokupheka zokupheka.

Isifundo Sefundisa e-Miami: Akukho kuthiwa kwezinto zokugqibela noma ukuguqula kwesikhathi sokuphakamisa kwe-98% RH

Ukufakwa kwe-2023 emsebenzini wase-Miami, owabhekisele ku-restaurant yamaphuthu amanzi, wabhekisele ku-test yokuphatha kwezinto eziphakeme: ubukhulu bekugcina kwesikhebe sokukhanya kwasemthwakathini kweba kuzo zonke izinsuku ngokubheka kwezinkamba, ukusika, nokucwashwa amathotho. Emva kwezinsuku ezimibili nezintandathu zokusebenza ngaphandle kokunqamuka, izihlalo zesikhebe sezimpahla ze-PVC zazisibonisa ukungabi nokuqondwa, akukho kuchaza kwezihlanu, futhi akukho isibonelo sokuhleba noma ukuthi kubekwe inkulumo yezinto ezingaphansi. Ukucwashwa ngosuku sonke ngezinkulumo zokucwashwa ezinamakhulu—okuyizindlela ezenza ukuthi izikhanda zokubhala noma izimpahla zomkhosi zihlale zihlabe kusheshaku—kubeka isikhanda esihlanu nesikhanda esisobala sasibona ngokuphelele. Lokhu kuhambisana ne-study ya-2022 e- Journal of Building Engineering , okwakubeka ukuthi izihlalo zesikhebe sezimpahla ze-PVC emizini yezindawo zokwenza amaphuthu emhlabathi ephelele kubonakala kahle kunezimpahla zokubhala noma izimpahla eziningi zokubhala, kanye nokuhleba—kubeka ukuthi ziyisifundo esingapheliyo sokubhekisele kwezindawo zokuphatha kwezinto eziphakeme.

Izidingo zokuhleba zezihlalo zesikhebe sezimpahla ze-PVC emizini yezindawo zokuhlala

Ukuvula izindawo zokuhlala kwezinkulumo: PVC vs. izimpahla ezingaphansi njenge-mineral fiber

Ukuphakanyiswa kwe-bathroom kuyisikhundla esiphambili sokudala kwe-biofilm—ilayiya yebakteriya eyodwa, eyadlula emaphakathi aphakathi amandla okukhanya. Isithembiso sesurfase siyisidingo esiphambili kakhulu. Amaphaneli we-PVC ase-ceiling ayizokwenzela ngokuzenzakalelayo, abonisa isurfase esingasenzi isibonelo sokubhukuda umshumayeli noma ukukhanya, futhi abhekise amicrobes ngokuphelele ekhaya labo lokufaka nokuphanda. Ngaphandle kwalokho, izinto ezinamaphakathi njenge-mineral fiber tiles ziyabonakala njengamaphakathi, zibhukuda umshumayeli ngaphakathi kwabo. Nangokusebenzisa amacoating esurfase, lezi zinto zibhukuda umshumayeli, zidala izindawo ezingavisiyo, ezikhiywa ngokuphelele, ziyabonakala njengamaphakathi okudala kwe-biofilm.

Isiphumo sokusebenza sibonisa ukuthi isikhumba senkantolo siyisikhumba esihle kakhulu. Ngokuzimela ukuthi isikhumba siphatha amanzi, i-PVC ishisa ngokushesha emva kokubhalwa ngokushisa—sivula ikheli lokuphakama kwezinkokhelo okudingekile ukuthi izinhlobo nezibhakteriya zizwe. Ukuchaza kwesikhumba kuyisibonelo sokuhlela isikhumba sokusebenza, okwenza i-PVC isikhumba esihle kakhulu ekulungiseni ukuthi isikhumba sibe nesibhakabhaka esikhulu kuleyo inkantolo.

Ukucisha okungafanele ukuthi kwenziwe ngokushesha nokubaluleka kwezikhumba zokugcina

Ukuhlanganiswa nezincwadi zezincwadi zase-EPA zokucisha nokubaluleka kwezikhumba zokucisha ngaphezu kwezikhumba zokucisha

Isilwane sesandla sokugcina amaphaneli we-PVC esikhathini sekhaya nasekithinini sibiza umphumela wokucisha okuphelele. Ngaphandle kwezinye izinto ezisemthethweni zokubhala (drywall) noma izitayile zeminerals—ezihambisana nemvula nezinkambo zokucisha—isandla sokugcina esiphakathi kwesipolimha sibeka izinkambo zokucisha emuva kwezinye, apho zisebenza ngokuphelele, futhi kusivumela ukukhupha kabusha ngaphandle kokubeka imithombo yezinto ezingavumelekile. Ukubaluleka kwakhe kwezinkambo zokucisha kusivumela ukusebenzisa izinkambo zokucisha ezinkulu, njengokwesifundo sika-EPA List N njengezinkambo zokucisha zokubhala (bleach) ezincinci, ngaphandle kokuguqula isandla. Emthwakathwaka wokuziphatha kwezinsizakalo zokufunda izinto, umphakathi wokucisha wokuphakathi kwezinhlangano zokufunda izinto, amaphaneli we-PVC asezinga eliphelele ayagcina 500 izikhathi zokucisha okuphakathi. Amaphenya abonisa ukuthi akukho mguqulo wokubonwa kwezinkimbinkimbi, umbala, noma isandla (Isiripoti sokuqinisa kwezinye izinto, 2023). Lokhu kusivumela ukuthi isandla noma isikhundla sibe phakathi kwezinye izinto ngaphandle kokuguqula—ngaphandle kwezikhaya zokusebenza ezidinga ukucisha okuphakathi kwezinye izikhathi ngosuku. Ngokucisha okuphakathi kwezinye izikhathi, amaphaneli we-PVC asivumela ukuthi isikhundla sibe salungile ngokuphelele, ngaphandle kokubeka izinkambo eziningi noma ukwenza izindlela zokuhlinzeka.
